This converts the usage of strtod to av_strtod in order to unify and
make number parsing more consistent. This also adds support for SI
postfixes.

Many of the functions from avfilter/formats can return errors, usually AVERROR(ENOMEM).
This propagates the return values.

All of these were found by using av_warn_unused_result, demonstrating its utility.

Tested with FATE. I am least sure of the changes to avfilter/filtergraph,
since I don't know what/how reduce_format is intended to behave and how it should
react to errors.

Fixes: CID 1325680, 1325679, 1325678.

Do not leak the initialized filter instance.

This is shorter and consistent across filters.

Deprecate AVFilterBuffer/AVFilterBufferRef and everything related to it
and use AVFrame instead.

%f denotes a double argument and 'l' does nothing in this case
according to the C spec.

Any alleged performance benefits gained from the split are purely
mythological and do not justify added code complexity.

Allow to accept paths with no ending trailing slash.

Fri0r project moved from piksel.org to frei0r.dyne.org.

A number of compilers, for example those from TI and IBM, choke on
these initialisers.  The current style is also quite ugly.

This reduces code duplication and prevents stale pointers from remaining
